Technical Field

The invention belongs to the technical field of rolling bearing testing machines, and particularly relates to a bearing seat device capable of measuring running parameters of different positions of a bearing.

Background

The cylindrical roller bearing is widely applied to mechanical transmission systems such as main shafts of aircraft engines, gear boxes, robot speed changing devices and the like due to the advantages of small friction factor, excellent high-speed performance and the like. For a cylindrical roller bearing which operates at a high speed, frequent collision and friction between the rollers and the retainer cause the temperature in the bearing to rise, and the rollers slide relative to the roller paths in a high-speed and light-load state, so that the revolution speed of the retainer is reduced. Studies have shown that unstable operation of the bearing at high rotational speeds due to frequent roller-to-cage collisions and friction between the roller raceways is often the primary cause of bearing failure. Therefore, it is very important to measure the operating parameters of the high-speed cylindrical roller bearing, such as temperature, the rotating speed of the retainer, etc., in real time, and therefore, the bearing seat is often required to be provided with a temperature measuring device, an ultrasonic probe, etc. If the bearing operating parameters of different positions of the bearing are measured, through holes are required to be drilled at different positions of the bearing seat, but the complexity of the structure of the bearing seat is increased, the structural strength of the bearing seat is reduced, and the sensor is frequently mounted and dismounted when the loading position of the sensor relative to the bearing is changed, so that inconvenience is caused.

In addition, the frequency of frequently mounting and dismounting the sensors when the sensors measure the running parameters of the bearings at different positions can be reduced, the requirement that the sensors measure the running parameters of the bearings at a plurality of positions is met, the positions of the opposite bearing loading points can be quickly changed by the sensors, the temperatures and the rotating speeds of the bearings at different positions can be effectively measured, and the device has the advantages of simple structure, high stability and strong adaptability.

The invention is realized by adopting the following technical scheme:

a bearing seat device capable of measuring operation parameters of different positions of a bearing comprises a bearing seat and a tension loading device; the bearing seat is used for mounting a rolling bearing, and a temperature sensor, an ultrasonic sensor and a tension loading device are respectively mounted in the circumferential direction of the bearing seat.

The invention has at least the following beneficial technical effects:

When signals such as outer ring temperature, retainer rotating speed and the like in real time of bearing operation are measured, the sensors are not required to be frequently detached. The temperature sensor can measure the temperature of the outer ring, and the ultrasonic sensor can acquire bearing signals such as the rotating speed of the retainer. And the loading position is changed by disassembling the tension sensor and the rotary bearing seat, so that the sensor can measure the operating parameters of the bearing area and the non-bearing area of the bearing.
